Steve, this is not uncommon. Being brass the terminals are relatively soft and liable to wear. Not being complete circles they are often overtightened at which point they, as you say, become liable to fatigue. For all these reasons you have to be gentle with them. I have never tried to replace them but it might work. Firstly though I would try to find a grub screw which is unworn and therefore fits better. Also I would tin the wire ends so that they grip better on tightening. You could of course go the whole hog and just solder the wires in! It would make things awkward if you need to take them out again but it would solve the problem, and how often do you remove these wires anyway? Good luck Ian Thomson Notts. UK.

It will indeed deform, and be tight initially, but will in time allow the wires to get loose. You could get hold of a cheap RF95 (from a TD, so plentiful) and break it up. This will give you several terminals and two coils (those more fsamiliar with such things will be able to confirm whether or not they are the same as RF91 coils) BTW I have new brass terminal screws! cheers Roger On Fri, Sep 21, 2018 at 9:23 AM ian thomson i.thomson@talk21.com [mg-tabc] mg-tabc-noreply@yahoogroups.com> wrote: [u][/u] Re: "Has anyone successfully replace the grub screw terminals on the control box?"

The softness of the solder may lead to a slight easing of the tinned wires with the degree of this being affected by how tight they are done up in the first instance. This also happens though when the wires are untinned as the individual strands move relative to one another leading to a slight loosening with time. Tinning will not allow this movement. What I am saying is both methods will allow a degree of loosening with tinning arguably leading to less. Arguably tinning of the ends also allows the strand bundle to conform better to the shape of the pillar and grub screw affording a better contact in spite of the slight easing of the grip.
